Abstract
A digital electronic watch has a time display section for displaying in digital form the time in minutes and hours and a remaining-time display section for displaying the time remaining within one of several different preselected time periods. The remaining-time display section includes a series of liquid crystal panels capable of being turned ON and OFF, and an electric circuit is provided for sequentially energizing or deenergizing the panels at predetermined time intervals to progressively turn ON or OFF the liquid crystal panels whereby the panels collectively provide a shining or brightness indication of the time remaining within the selected time period. A manual switch is provided to manually set the desired time period whose remaining duration is to be displayed and an audible alarm signal is emitted in response to the expiration of a predetermined portion of the selected time period.
